Description

Technical Field

[0001] The present invention relates to the field of BIM technology, and in particular to a method for implementing a complex space hyperbolic roof based on BIM forward design. Background Art

[0002] With the development of BIM technology and domestic software, the technical path of forward design based on BIM technology is becoming clearer. However, due to the fact that traditional design and production methods are difficult to transform in a short period of time, related technologies are not mature enough, and there is a shortage of related talents, the application of forward design based on BIM technology has not been widely promoted.

[0003] For example, a Chinese patent discloses a method for manufacturing and installing a complex space curved surface special-shaped steel box girder based on BIM technology (publication number: CN110886186A). The complex space curved surface is a vertical curve and a flat curve with variable curves. The special-shaped steel box girder is a steel box girder with a constantly changing cross-section and a non-fixed shape. The manufacturing of the special-shaped steel box girder includes virtual splitting, parts deepening, intelligent layout, and digital cutting and blanking of the steel box girder based on the assistance of a three-dimensional model. The installation of the special-shaped steel box girder includes virtual pre-assembly based on the assistance of a three-dimensional model, construction plan deepening, and actual installation and welding on site. The use of three-dimensional visualization means to assist in the deepening of parts ensures the processing accuracy of parts, reduces the defective rate and material loss rate, and is more convenient to control the surface curvature and overall accuracy of the component based on the assistance of three-dimensional technology, improves the production quality of the component and the accuracy of on-site installation, and at the same time improves the efficiency of on-site management through virtual pre-assembly, reduces safety risks, and reduces quality and safety accidents.

[0004] The complex spatial hyperbolic prefabricated roof structure has the characteristics of complex structure, difficulty in spatial positioning, abstract shape, and difficulty in drawing elevation drawings. It is difficult to split the components, calculate the reinforcement, and produce. It is not conducive to the design, production, construction, model display and other work.

[0005] Therefore, it is necessary to propose an implementation method for complex spatial hyperbolic roof based on BIM forward design to solve the above problems. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an implementation method of a complex spatial hyperbolic roof based on BIM forward design to solve the above-mentioned problems.

[0009] S2, assembly design and drawing;

[0010] S3. Production assistance and model display: guiding workshop production and model effect display through BIM technology.

[0011] The BIM forward design in step S1 improves design efficiency and helps designers to intuitively experience the modeling effect.

[0012] In step S2, the assembly design and drawing use BIM software to complete component splitting, assembly calculation, and detailed structure deepening.

[0013] The model display in step S3 uses BIM technology to output the roof structure model, which helps the construction unit, supervision unit, construction unit, and production unit to understand the design intent.

[0014] Among them, the production assistance in step S3 uses BIM technology to guide the production of prefabricated complex spatial hyperbolic roof panel components in the workshop, assist in steel bar positioning and template elevation control, and help improve the qualified rate of finished products.
